Abstract:
Five new macrocyclic napyradiomycins with different types of scaffolds were isolated from marine-derived Streptomyces canus SJ-019. Compounds 1 and 2 are uniquely typified by a spirocyclic core, while 1, 2 and 4 also contain a unique macrolide structure not known in any other napyradiomycins. Compound 3 is composed of a dearomatized napyradiomycin core and an intramolecular double-arch bridge system. Compound 4 displays potent inhibition of Staphylococcus aureus, while C-type napyradiomycin 5 shows notable anti-inflammatory effect.
